SASI-I-HOLDER.

Specification of Letters Patent.

Patented Beet, 11915.

Application filed May 8, 1911. Serial No. 625,904.

To all whom it may concern:

Be it known that 1, JOEL T. HART, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Sash-Holders, and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

My invention relates to sash holders of the kind for which I obtained United States patent, February 18, 1896, and theobject of my invention is to so change the construction of said patented sash holder as to simplify, cheapen and otherwise improve the same.

With this object in view, my present invention consists in the sash holder constructed substantially as hereinafter specified and claimed.

In the accompanying drawingsFigure 1 is a perspective view of a portion of a window with my sash holder showing posi tion for use; Fig. 2 is a vertical section thereof on a plane at right angles to the axes of the levers; and Fig. 3 a section on line 3-3 of Fig. 2.

As in the case of my previously patented sash holder, I employ two reversed but otherwise similar cam carrying levers 10, each having a handle 11 on one side of its pivot and on the other side of its pivot having a cam 12 with a roughened face adapted to engage the edge of the window bead .13, or if preferred, a corrugated or roughened strip of metal 14: fastened thereto to avoid wear of the wooden bead. The cam members of both levers are yieldingly pressed toward each other and against the window head by means of a spring consisting of a coil 15 having two tangentially extending arms 16, each ofwhich arms engages the cam member of a lever which is notched or slotted to receive the spring arm sothat the latter is prevented from vsidewise or lateral movement and thus in that regard is maintained in a fixed position laterally with reference to the lever. The spring with its two arms, it will be seen, is V- shaped. Both the levers are pivoted on the same tube or thimble 17 and the coil of the spring is also placed thereon, a rivet 18 passing through the tube or thimble and through the opposite walls of the casing securing the same in position.

The coil is superimposed above and upon the levers, and therefore in the order of assembling the parts is placed on the thimble last, or after the levers are in place, which enables the spring arms to be readily turned into a state of tension, and then set into engagementwith the levers, after which the cover plate of the casing may easily be mounted on the base plate and rivet, thus securing all the parts in place. Also by this constructionthe tension of the spring arms may be so adjusted with relation to the coil that they will exert slight pressure upon the levers to hold them against the base plate and corresponding reaction of the coil against thecover part of they case,

which will prevent rattling or shaky action of the levers in the case, without imposing material friction on the parts, the frictional surface of the spring being confined to the area close to the axis of the parts with consequent reduction ofmovement.

It will thus be seen by the employment of a single element for pivoting the levers, mounting a spring and connecting the op posite walls of the casing together, 1 produce a most simple, inexpensive, compact and yet wholly eflicient device. The casing consists simply of two strips of sheet metal, a simple straight piece 1.9 that forms the base and which goes next to the sash bar when the holder is applied to the sash, and the other a strip of sheet metal 20 which is bent down at one edge to form a flange 21 that constitutes a side wall of the box or casing, it being notched for the play of the levers, and which is also similarly bent at each end to form top and bottom walls and is again. bent parallel with the piece or strip 19 to form a foot through holes in which and holes in the strip 19 screws are passed to attach the device to the window. Said attaching screws by reason of their location can be short screws and they can easily be applied. The casing being formed of sheet metal as I have described, especially by reason of the presence of the side forming flange 21, is not only neat looking but it is very strong. It is desirable to limit the extent of the movement of the levers and the spring arms, and thus prevent likelihood of breakage of the spring by excessive movement. 1 provide for this from the base piece or strip 19 atongue'or lug 22 in position to engage eachleverat- 9 space the box or casing plates 19 and 20- sufliciently far apart to avoid any rubbing of the spring arms on the box sides, and thus friction is avoided, which in practice has been found objectionable in that it renders hard the operation of moving. the levers to free the cams from engagement with the window'frame. Again-the cams are inclosed except for the slight protrusion necessary to give them a grip on the bead, and thus danger of the cams and the free ends of the spring arms catching into and tearing lace curtains and injuring the hands is obviated.

1 Having thus described my invention what I claim is A- sash holder having a box or casing formed of two sheet metal members one of of which is bent toward the flat straight piece to form a side wall and top and bottomwalls, said flat straight piece projectingbeyond said; top and bottom Walls, and

each projecting portion being overlapped by an outturned foot extending from the contiguous end wall, said foot and the overlapped portion of the flat straight piece having alini-ng holes for the reception of a fastening screw, a pair of cam carrying levers pivoted between said members, a douconstituting the pivot for both said levers,

the two levers overlying one another at the pivot and each lever being crossed by one of the spring arms where it extends from the coil to the point of engagement of the spring arm with its lever, and the lever at the point of engagement having a notch which receivesthe outer end portion of said spring arm, the coil of the spring being mounted on said pivot, above and superimposed upon the lovers with compressive tension exerted between the levers and case plate to seat the lovers against the straight flat base piece otthe case, and a stop for each lever consisting of a tongue struck up from said straight flat piece.

In'testimony whereof I aflix my signature in presence of two witnesses.
